1.4. Image Viewer Features

Image Viewer has a variety of features to help you view your images. You can zoom in and out or view the image full screen. Regardless of your zoom level, Image Viewer uses a low amount of memory. You can also rotate and flip the image you are viewing.

The collection view allows the viewing and editing of large image collections. In this view image operations can be applied to all selected images at once.

Image Viewer has special support for digital camera pictures and displays EXIF metadata recorded with the image. This feature requires libexif to be installed on your system. All modifications made in JPEG images are lossless. That is, saving rotated and flipped JPEG images will not recompress the image. Beside this all available metadata (like EXIF) will be preserved and updated accordingly.
